C ++ DNA翻译问题 [英] C++ DNA translation problem

问题描述

我正在尝试制作一个程序，可以使用模板DNA并显示转录和翻译后形成的氨基酸序列

它有效，但仅适用于3个碱基。我希望它尽可能多地工作。

这就是我所拥有的：



我尝试过：

I am trying to make a program that can take Template DNA and show the amino acid sequence that is formed after transcription and translation
It works, but only for 3 bases. I would like it to work for as many bases as possible.
This is what I have:

What I have tried:

#include <iostream>
#include 
#include <string>

using namespace std;

typedef std::map<std::string, std::string> TStrStrMap;
typedef std::pair<std::string, std::string> dnaTemplatePair;

int main(int argc, char *argv[])
{
	TStrStrMap oMap;

	oMap.insert(dnaTemplatePair("TTT", "Phe"));

推荐答案

你应该这样做：

You should do something like that:

int n = dnaTemplate.size()-2;
for (int i = 0; i < n; i+=3)
{
   std::string triplet = s.substr(i, 3);
   std::string aminoacid = oMap[triplet];
   ...
}

你需要找到并获得一些数据库（互联网，同事或学校）而不是写一些代码使用它。这是小菜一碟。

You need to find and get some database (internet, collegues or schools) and than write some code to work with it. This is a piece of cake.

不，紧接在

No, immediately after

std:: cin >> dnaTemplate;

行

The line

std::string strValue = oMap[dnaTemplate];

不正确：您正在尝试将整个字符串用作地图中的索引。你应该一次使用一个三元组。

is incorrect: you are trying to use the whole string as an index in a map. You should use one triplet at a time.
